Answer:
12 books
Step-by-step explanation:
Lets set aside $25 for dinner first.
Amount left = $230 - $25 = $205
Number of books able to buy = amount left ÷ cost per book
= $205 ÷ $17
= 12.058 books
Of course, you cant buy .058 books , that wont make sense, so you take the highest possible WHOLE number, which in this case, is 12 books.

The general quadratic equation is
Ax² + Bx + C = 0 .
The roots are real only if (B² - 4AC) is not negative.
That means if you graph it, it touches or crosses the x-axis.
If the graph is up in the air and never touches the x-axis,
then it has no real roots.
